axum-debug
This is a debugging crate that provides better error messages for axum
framework.
axum
is a great framework for developing web applications. But when you
make a mistake, error messages can be really complex and long. It can take a
long time for you to figure out what is wrong in your code. This crate provides
utilities to generate better error messages in case you make a mistake.
Usage Example
Will fail with a better error message:
use axum::{routing::get, Router};
use axum_debug::debug_handler;
#[tokio::main]
async fn main() {
let app = Router::new().route("/", get(handler));
axum::Server::bind(&"0.0.0.0:3000".parse().unwrap())
.serve(app.into_make_service())
.await
.unwrap();
}
#[debug_handler]
async fn handler() -> bool {
false
}
Error message:
error[E0277]: the trait bound `bool: IntoResponse` is not satisfied
--> main.rs:xx:23
|
xx | async fn handler() -> bool {
| ^^^^
| |
| the trait `IntoResponse` is not implemented for `bool`
Safety
This crate uses #![forbid(unsafe_code)]
to ensure everything is implemented in 100% safe Rust.
Performance
Macros in this crate have no effect when using release profile. (eg. cargo build --release
)
